Abstract: A fire fighting simulator includes a projector to project an image of a fire on a screen and a shutter assembly to occlude portions of the image. The extinguishing agent is simulated by an infrared beam and the shutter assembly is controlled to occlude portions at locations impinged by the beam. The control also polls each element of the shutter assembly periodically and opens the elements selectively to simulate reflash of the fire.

Abstract: An electronic article surveillance system has a receiver with a plurality of receiving coils. Each coil in the system is treated as a separate detection unit with its own noise environment which is distinct from the noise environments of the other coils in the system. The picture of the noise environment is preferably expanded to include examining noise per coil per phase. Control apparatus has facility for changing the interconnection and configuration of the receiving coils responsively to the per coil and per phase noise environment analysis. Noise analysis and coil configuration change can be practiced concurrently with EAS system operation or may be practiced during periods in which the EAS system is rendered inactive.

Abstract: A wall anchor uses splines on an interior surface of a  cylindrical  body  to  accommodate  fasteners  having different thread diameters.  The splines are configured in types.    A  first  type  includes  at  least  one  spline protruding centrally at a narrow angle, while a second type also includes at least one spline protruding centrally at a wider angle.  When a fastener, such as a #6 or #8 sheet metal screw (SMS), is inserted into the wall anchor, the first type of spline will primarily engage the #6 SMS, while  the  second  type  of splines  are  only  partially implemented.   When a #8 SMS, which has a larger thread diameter than a #6 SMS, is inserted into the wall anchor, both the first and second types of splines are engaged to facilitate retention of the SMS.

Granted: 2006-10-10
Abstract: A system to enhance query performance. The query is performed on a modified database in which data entries for each field are stored contiguously across all records. The query is parsed (32) into portions directed to each field referenced by the query. Each portion is searched ove r the contiguous entries of the appropriate data field. A bitmap is generated (36) by producing a string of bits, each bit representing a record and setting bits corresponding to records that satisfy the query. The resulting bitmaps are combined (38) to produce the results of the original query. The preferred embodiment is a direct marketing database on a client server system using a spreadsheet like interface for query manip ulation. Data segmentation, ad hoc requests and systematic research are allowed. A suite of reports specifi c to the needs of direct marketers may be produced on a regular basis.

Abstract: A system to monitor the temperature of an integrated circuit and to dissipate heat generated thereby includes a heat sink to overlie the integrated circuit. A temperature sensor is located on the heat sink to detect the temperature adjacent the integrated circuit. Temperature signal conditioning circuitry is responsive to the temperature sensor and generates a temperature alarm signal when the temperature at the integrated circuit reaches a threshold level. A fan overlies the heat sink and draws air across and then away from the heat sink to cool it. A pressure transducer is mounted on the fan and detects air flow through the fan. Pressure signal conditioning circuitry is responsive to the pressure transducer and generates a pressure alarm signal when the air flow through the fan falls below a threshold level. Alarms are triggered by the temperature and pressure alarm signals to warn a user.
